Vestibular neuritis is a common acute disease of the vestibular system in otology. Patients often present with acute episodes of vertigo and balance disturbance, with a strong sensation of rotation (the feeling that all surrounding objects are turning around oneself or rolling from side to side, back and forth), and the vertigo symptoms are aggravated by head movements or position changes and last for a relatively long time (ranging from about hours to days). At the same time, patients often have autonomic symptoms including physical discomfort, pallor, sweating, nausea, and vomiting; however, symptoms in the ear are often not obvious, such as tinnitus, a sense of ear swelling and hearing loss, etc. Most of the symptoms are not accompanied by tinnitus. The exact etiology and pathogenesis are not well understood, but are currently thought to be related to viral infection of the superior vestibular nerve; therefore, some patients often present with some clinical manifestations of a viral cold before the onset of the disease. The auxiliary diagnostic aspects of vestibular neuritis include: pure tone audiometry, acoustic conductance, brainstem auditory evoked potentials, as well as vestibular myogenic evoked potentials and vestibular function tests to differentially diagnose vertigo caused by related intra-aural diseases. CT brain examination is also performed to rule out central lesions such as cerebellar hemorrhage or infarction. If the patient has a normal pure tone hearing threshold, no associated ear symptoms, as well as no abnormality on cranial CT, but only shows symptoms of isolated vertigo of long duration; then the diagnosis of vestibular neuritis can basically be considered.
